4 Claims.

This invention relates to bale ties, and it is primarily an object of the invention to provide a joint lock for the steel strapping ties or bands which are now generally used at cotton mills in 5 the baling of cloth.

It is also an object of the invention to provide a joint lock of this kind which when effective will resist all strain imposed thereupon and thus assuring desired holding of the bale.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved self lock for a bale tie whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter he definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:--

Figure l is a view in elevation of a joint lock of a bale constructed in accordance with an embodiment of my invention;

Figure 2 is an enlarged view partly in section and partly in elevation of the joint lock as illustrated in Figure 1;

Figure 3 is a sectional View taken substantially on the line 33 of Figure 1;

Figure 4 is a view partly in side elevation and partly in section of the lock as herein disclosed with the parts separated;

Figure 5 is an enlarged sectional view taken substantially on the line 55 of Figure 1.

As illustrated in the accompanying drawing, B denotes the end portions of a steel strapping tie or band such as now generally employed in cotton mills for the baling of cloth. These ties or bands in practice are of a length to be properly disposed around the tie. Each end portion of the band or bale is provided with the overlying folds l and 2 in closecontact one with the other and with the fold 2 interposed between the fold I and the adjacent portion of the band or tie B and in close contact therewith. These folds l and 2 are of material length and the juncture between the folds and 2 provides a shoulder 3 facing inwardly of the band or tie B. The folds I and 2 are integrally connected, the fold 2 being in continuation of the fold l. The fold l is also integrally formed with the band or tie B and constitutes a continuation thereof.

When it is desired to make the lock effective the extremities of the band or tie B are brought into overlying relation as illustrated in Figure 4, and the inwardly facing shoulders are brought into substantially abutting relation whereupon is slid over said extremities or end portions of the band or tie B the holding buckle 4. This buckle 4 is preferably of a length substantially equal to the combined lengths of the folds I so that when the lock is effective the folds l and 2 at both end portions or extremities of the band 5 or tie B are substantially housed within the buckle 4 as is clearly illustrated in Figures 1, 2 and 3 of the accompanying drawing.

The buckle 4 is of tubular formation and in cross section the central opening or bore of the 10 buckle 4 substantially conforms to the cross sectional configuration of the folds l and 2 plus the thickness of the adjacent portions of the tie or band B proper. It is to be understood that with the buckle 4 in effective or looking position the 15 extremities or end portions of the tie or band B and the folds carried thereby are snugly received within the buckle 4 whereby the desired coaction between the shoulders 3 assures a maximum of efficiency. It is to be stated that the 20 buckle 4 will be maintained in working position at all times or against accidental slippage into inoperative position as a result of the inherent outward pressure exerted by the cloth in the bale. 5

While it is believed to be obvious it is now explained that before a lock is effective an end portion of the band or tie B is threaded through the buckle 4 as is clearly indicated in Figure 4 of the drawing. 3

From the foregoing description it is thought to be obvious that a self lock for a bale tie constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be as- 35 sembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed. 45

I claim:

1. In combination, a bale band having overlying folding portions at its extremities to provide inwardly facing shoulders, said shoulders abutting when the extremities of the band are in oVer- 50 lapping relation, the opposed faces of the folding portions being in close contact at all points, and a buckle for holding said extremities in overlying relation.

2. In combination, a bale band having overly- 55 ing folding portions at its extremities to provide inwardly facing shoulders, said shoulders abutting when the extremities of the band are in overlapping relation, and a buckle for holding said extremities in overlying relation, said buckle being 0 tubular and slidable along the band and freely receiving the folding portions.

3. In combination, a bale band having overlying folding portions at its extremities to provide inwardly facing shoulders, said shoulders abutting when the extremities of the band are ino-verlapping relation, and a buckle for holding said extremities in overlying relation, said buckle being tubular and slidable along the band, the extremities of the band and the folds being freely and snugly received within the bore of the buckle with the shoulders abutting.

4. A tie bale having overlying folds at its end portions, said folds at each end portion being in close contact one with the other with one of the folds in close contact with the band proper, said folds being integrally connected and the outer fold being integrally connected with the band, the folds at the extremities of the band providing inwardly facing shoulders for abutting contact when the extremities of the band are overlapped, and

means for holding the extremities of the band 10 overlapped with the shoulders abutting.
